How many tenths are there in 4/5

il63 [147K]

What we have to solve is:

$\frac{4}{5} = \frac{x}{10}$

we should multiply both sides by10, to get the "x" by itself:

$\frac{4*10}{5} = \frac{x}$

$\frac{4*2}{1} = \frac{x}$

$8 = \frac{x}$
so there are 8 tenths in this number!

Selma cannot remember her locker number! She knows that her locker number is prime, and that it is a factor of 435. What are all

tatuchka [14]

Answer:

Possible locker numbers for Selma are: 3, 5 and 29

Step-by-step explanation:

First of all, let us have a look at the definition of a prime number.

A <em>prime number</em> is a number which is divisible either by 1 or the number itself.

No other number divides the prime number other than 1 and the number itself.

Now, let us factorize the given number 435 and let us observe the what all possibilities are there.

$435 = 3\times 145$

Factorizing 145 further:

$435 = 3\times 5\times 29$

No further factors are possible.

Therefore 3, 5 and 29 are the prime factors of 435.

So, the answer is:

Possible locker numbers for Selma are: 3, 5 and 29
